Financier

Bollingers appliqués au bandes de

II. Comment on calcules ces bandes ?
II. Comment on calcules ces bandes ?
• Tout d’abord, on calcule la MMA20
Rappel: MM(n) = (C1 + C2 + … + Cn) / n
• Bande supérieure: MMA20 + 2 * l’écart type
Ecart type: 𝑛(𝑐𝑙𝑜𝑡𝑢𝑟𝑒 − 𝑀𝑀(𝑛))2/𝑛
• Bande inférieure: MMA20 – 2 * l’écart type
• Elles représentent la volatilité du cours, 95% des valeurs se
trouvent entre les bandes
• Si les marchés sont volatils, les bandes sont éloignés.
III. Comment on les utilises ?
III. Comment on les utilises ?
• Les changements de prix majeures ont tendances à arriver
après un resserrement des bande (d’un état peu volatil à très
volatils)
• Si les prix sortent des bandes, c’est que la tendance à suivre
• Point 1: un petite sortie, du bas sort, puis vers le haut rentre,
les prix vont monter (indicateur très réactif)
• Point 2: l’inverse est vrai
• Si on frôle une bande, c’est que on ne va pas tarder à aller
frôler l’autre coté
IV. On veut des exemples !
C’est parti pour le trade en Live !!!!
